Undo faith in GRUB and RH7.3 means I can't access my XP partition. Please help.

Actually, IIRC, you should be able to boot XP by adding the following
commands to GRUB's menu.lst file (usually located in /boot/grub):

	title Windows XP
	root (hd0,?)
	chainloader +1
	
Since GRUB loads it's config directly from the filesystem, you don't
have to re-run it after the edits. Alternatively, when GRUB's menu comes
up you can press 'c' to get to a command prompt and issue the following
commands to boot XP:

	root (hd0,?)
	chainloader +1
	boot

Replace the ? with the partition number of wherever XP is installed.
Keep in mind, though, that GRUB's partition numbers start from zero, so
hda1 = (hd0,0)
